Here is a very interesting article from John Witherspoon over at Anything Wine. John references this article in the Seattle Times, which argues that cork usage is actually better for the environment than screw caps. The gist of it is that cork trees are not killed in the process of making corks, and that the process actually helps to keep them healthy over their 200-year life span.
I find this very interesting. While I have become a believe that screw caps are the better enclosure for the wines, red and white, I think the effects on the environment should be carefully considered, especially since wine is ultimately an agricultural business. Does anyone have any thoughts on this? I would be curious to hear if there is an environmental argument for screw caps.
